Unlike modern Internet datagrams, the ARPANET was designed to reliably transmit 1822 messages, and to inform the host computer when it loses a message; the contemporary IP is unreliable, whereas the TCP is reliable. Nonetheless, the 1822 protocol proved inadequate for handling multiple connections among different applications residing in a host ...
Ultimately his vision led to ARPANet, the precursor of today's Internet. [19] After serving as manager of information sciences, systems and applications at IBM's Thomas J. Watson Research Center in Yorktown Heights, New York from 1964 to 1967, Licklider rejoined MIT as a professor of electrical engineering in 1968.
The history of the Internet originated in the efforts of scientists and engineers to build and interconnect computer networks.The Internet Protocol Suite, the set of rules used to communicate between networks and devices on the Internet, arose from research and development in the United States and involved international collaboration, particularly with researchers in the United Kingdom and France.
David Corydon Walden (June 7, 1942 – April 27, 2022) was an American computer scientist and Internet pioneer who contributed to the engineering development of the ARPANET, a precursor of the modern Internet. He specifically contributed to the Interface Message Processor, which was the packet switching node for the ARPANET.
This process is important because ARPANET would eventually merge with other networks to form the Internet and many of the protocols the Internet relies upon today were specified through this process. The first Transmission Control Protocol (TCP) specification, RFC 675 ( Specification of Internet Transmission Control Program ), was written by ...
The Interface Message Processor (IMP) was the packet switching node used to interconnect participant networks to the ARPANET from the late 1960s to 1989. It was the first generation of gateways, which are known today as routers. [1] [2] [3] An IMP was a ruggedized Honeywell DDP-516 minicomputer with special-purpose interfaces and software. [4]

On the ARPANET, the protocols in the physical layer, the data link layer, and the network layer used within the network were implemented on separate Interface Message Processors (IMPs). The host usually connected to an IMP using another kind of interface, with different physical, data link, and network layer specifications.
